从javascript通过端口停止进程

Question

I'm using jest to write some tests for a node.js application. I have a server server.js and a test file server.test.js . In my server.js I use the line

    var secureServer = https.createServer(options, 
    app).listen(config.node_port, () => {
    logger.info("Service running on " + config.node_port)
    });

to start my server on port 8082. In server.test.js I use

    var posClient = require('./pos-ClientJS.js');

to get access to the functions, that I have to test. When I run my test I get the following console output:

    Jest did not exit one second after the test run has completed.

    This usually means that there are asynchronous operations that weren't 
    stopped in your tests. Consider running Jest with `-- 
    detectOpenHandles` to troubleshoot this issue.

So my question is: Is there a way to stop the server running with javascript code like stop(8082) or sth.? Or is there a less difficult way to solve this problem without stopping the process?

Answer 1

From the Nodejs HTTP module documentation, you can call secureServer.close() to stop listening at the specified port. If the module exposes the server to Jest, you can use the teardown methods to stop the server automatically after tests complete.
